- 6.49 Which of these electron configurations are for atoms in the ground state? In excited states? Which are impossible? (a) 1s22s1, (b) 1s22s22p3, (c) [Ne] 3s23p34s1, (d) [Ne] 3s23p64s23d2, (e) [Ne] 3s23p64f 4, (f) 1s22s22p43s2arrow_forwardGiven the valence electron orbital level diagram and the description, identify the element or ion. a. A ground state atom b. An atom in an excited state (assume two electrons occupy the 1s orbital) c. A ground state ion with a charge of 1arrow_forwardUsing orbital box diagrams, depict an electron configuration for each of the following ions: (a) Mg2+, (b) K+, (c) Cl, and (d) O2.arrow_forward
- What is the difference between core electrons and valence electrons? Why do we emphasize the valence electrons in an atom when discussing atomic properties? What is the relationship between valence electrons and elements in the same group of the periodic table?arrow_forwardThe following are orbital diagrams for presumed ground-state atoms. Several, though, violate Paulis principle or Hunds rule Which of the these follow both Paulis principle and Hunds rule, and which violate one or the other (state whether Paulis principle or Hunds rule is violated)? a b c d earrow_forwardr Questions 11—13, you will need to consider ionizations beyond the first ionization energy. For example, the second ionization energy is the energy to remove a second electron from an element. Compare the first ionization energy of helium to its second ionization energy, remembering that both electrons come from the 1s orbital. l> X Y First 170 200 second 350 400 Third 1800 3500 fouth 2500 5000 entify the elements X and Y. There may be more than one answer. so explain completely.arrow_forward
- From what you know in a general way about electron affinities, state which member of each of the following pairs has the greater value: a As, Br b F, Li.arrow_forwardUsing complete subshell notation ( 1s22s22p6, and so forth), predict the electron configurations of the following ions. (a) N3- (b) Ca2+ (c) S- (d) Cs2+ (e) Cr2+ (f)Gd3+arrow_forward2. How many orbitals are in the n = 4 shell? 1 4 9 16arrow_forward
- Which atom would be expected to have a half-filled 6p subshell?arrow_forwardValence electrons are those electrons in the outermost principal quantum level (highest n level) of an atom in its ground state. Groups lA to 8A have from 1 to 8 valence electrons. For each group of the representative elements (1A-8A). give the number of valence electrons, the general valence electron configuration, a sample element in that group, and the specific valence electron configuration for that element.arrow_forwardUse atomic orbital box diagrams to determine which chromium ground-state configuration has the greater number of unpaired electrons: [Ar] 3d44s2 or [Ar] 3d54s1.arrow_forward
